Abstract

Des modes de réalisation selon l'invention se rapportent à une DELO où l'extinction depuis une faible énergie de triplet dans la couche de transport de trous (HTL) au niveau d'une interface de couche HTL/couche d'émission (EML) dopée aux colorants avec un colorant phosphorescent peut être évitée lorsque l'énergie de triplet du matériau hôte pour la HTL est élevée, au-dessus de −2,6 eV, et le colorant phosphorescent de transport de trous se trouve à l'intérieur d'un matériau bloquant les électrons de transport de trous présentant l'énergie de triplet élevée et l'EML comprend le colorant phosphorescent de transport de trous. Le colorant peut se trouver dans la HTL à des niveaux supérieurs ou égaux à 3 %.
